Application filed January 17, 1918. Serial No. 212,240.

To all whom it may concern:

Be it known that I, JOHN ALFRED OLSEN,

a citizen of the United States, residing at Caribou, in the county ofKittson and State of Minnesota have invented certain new and usefulImprovements in Pliers, of which the following is a specification.

This invention relates to improvements in pliers and more particularlyto that class of pliers in which the grip jaws, as they are opened andclosed, so move relatively to each other that the contact faces of thejaws advance and recede toward and from each other in substantiallyparallel relationship. A further object is to provide pliers of thisclass comprised of few parts that consequently are cheap to manufactureand that are positive and eflicient in operation and that are of durableconstruction. 7

With the foregoin and other objects in view the invention consists inthe combination and arrangement of parts to be hereinafter fullydescribed, pointed out in the appended claims and illustrated intheaccompanying drawing which forms a part of this specification and inwhich- Figure 1 is a view in side elevation of my improved pliers.

Fig. 2 is a plan view of Fig. 1. j

Fig. 3 is a view in perspective of the guide plate employed.

Fig. .4: is a perspective view of one of the grip jaws.

Like reference characters denote corresponding parts throughout theseveral views.

The reference numeral 1 denotes the handles which are pivotallyconnected by the ed to the bars 8 by the pins 5, the said j aws 4: beingformed with the alined slots 6 which are disposed at right angles to thepins 5 and are of such shape as to snugly. receive the guide plate 7said plate being formed with the longitudinal edge ridges 8, 8 and withthe elongated slot 9 opening in its lateral faces. The jaws 4 are sosupported by topics of this patent may be obtained for five cents each,by addressing the fiommissioner of Patents,

the bars 3 that as said bars are separated the aws and gulde plate 7 maymove toward the handles 1.

Before the pins 5 are inserted to connect through the said slot 9 andthe tool is assembled. As the handles 1 are opened and closed the bars 3are opened and closed thus movlng the pins 5 toward and away from eachotherin the slot 9 of plate 7 which will operateto retain the contactfaces of the said aws 4 in parallel relationship, the jaws 4 beingseparated and moved deeper into the bifurcated end of the bars 3 by saidhandle movement. 7

What is claimed is j 1. In pliers comprising handlespivotally connectedand formed with inte 'ral terminally bifurcated bars, grip jaws isposedin the bifurcated portions of said bars, said grip jaws being formedwith alined slots, a

PlVOllfll connection between the said grip jaws and the said bifurcatedbars, and a guide plate slidably carried in the slotted portions of bothgrip jaws and slidably pivoted to both of said bifurcated bars.

2. In pliers comprising handles pivotally connected and formed withintegral terminally bifurcated bars, grip jaws terminally disposed inthe bifurcated bars, said grip jaws being formed with alined slots, apivotal connection between the said grip jaws and the said bifurcatedbars, said pivotal connection being disposed at right angles to thealined slots of said grip jaws, and a guide.

plate connecting the slotted portions of said grip jaws, said guideplate being formed with an elongated Islot receiving the pivotsI(onnecting the said grip jaws and bifurcated ars.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in the presence of two subscribing witnesses.
